Dumba didn't participate in Wednesday's practice session due to an upper-body injury, Brian Rea of FanDuel Sports Network Southwest reports.

EDGE Analysis

Dumba apparently sustained an injury during Sunday's win over Calgary, and he underwent further testing instead of practicing Wednesday. Head coach Peter DeBoer called Dumba's absence from practice a precautionary measure, but it's unclear whether he'll be available for Thursday's game against the Predators.
